34 Claims.

This invention relates to.,a tank or container in one piece with a closet bowl, or attachedtoit by suitable means. for the purpose of housing therein, a flush valve and other accessories, such as an air chamber, or a pressure reducing valve, or a strainer etc. or all, for thepurpose of elimimating the various inconveniences resulting at present in the use of flush valves in combination with a closet bowl, and to convey any leakage or exhaust from any or all of the said contrivances housed therein, into the bowl, as hereafter described.

(a) Danger of back-siphoniny.-There is no flush valve at present on the market that can be considered 100% siphon-proof; in fact, even a very small passage caused by corrosion, or by some matter lodged under the piston valve causing a leak of only about a gallon per minute, if vacuum occurs in the: supply pipeline, back-siphoning will occur, no matter what type of vacuum breaker, or any otherv such contrivance is used in combination with a flush. valve Independently of the practicability of such apparatuses, flush valves are at present not supplied with sufficient volume of air to break the vacuum in the supply pipeline; in fact, the largest air inlet that I know of, is only diameter; whereas to be efficient, an air inlet must be of the same diameter as the inside diameter of the supply pipeline, and must also be suitably located. A flush valve can be considered 100% siphon-proof only when back-siphoning does not. occur when the valve is operated under the following conditions, namely:

When the piston valve is completely open;

When no siphon breaker, no. check-valve or any other such contrivance is used, and

Whether or not the valve is in good working order.

. This invention answers to all these requisites in .full by means and in the manner hereinafter described.

.A. container, the interior of which is kept in constant communication with the atmosphere by means of an opening thereon, housing a flush valve, without the usual tail piece that connects said flush valve to the bowl and conveys the flush water into it, thus leaving an air space. between the top of the bowl and the outlet of the flush valve. Under such conditions it is obvious that it will be physically impossible for a vacuum of any intensity and duration to raise a drop of water from the bowl, thus positively preventing back-siphoning. To prevent the Water from spilling, but to convey it all into the bowl, a suitable funnel or a like. contrivance is provided, as shown in the appended drawings, and hereinafter described, which has answered the purpose under the most severe conditions, when this invention was reduced torpractice and tested, thus 5 proving that it is possible to obtain a 100% siphon-proof flush valve under the most severe conditions above described.

(b Noisy flushing.To eliminate this, the water is throttled by the control valve; this method is satisfactory as long as no other water is; withdrawn simultaneously when the flush valve is operated, otherwise it will fail to work. However, a pressure reducing valve could be used to eliminatev this inconvenience, but there is not always an adequate place where it can be installed. An appropriate place would be in the wall, within easy access for inspection or repairs, but in very few-cases the possibility for such a rational, arrangementpresents itself, but .a tank or-container, housing a pressure reducing valve will solve the problem in the neatest and most practical manner.

(0) Failure to flush-To obtain a quiet flushing. when the pressure in the main is too high, say 90 lbsthe water is suitably throttled by reducing theopening of the control valve, but if said 90 lbs. pressure-drops to lbs., and the flush valve is operated, the bowl will not flush; of course not for lack of pressure, but, because the reduced passage in the control valve is not sufliciently large to allow the full volume of water obtainable at the 20 lbs. pressure. In fact a flush valve will flush a bowl even at a water pressure as low as 10 lbs. 'if the full volume of Water at this pressure is available. This inconvenience-can be eliminated by a pressure reducing valyehoused in a tank, which will always give the full volume of water physically possible, at any pressure to which it has been regulated, unless thepressure in the main drops below that at which the pressure reducer is set.

, (d) Hammering -This inconvenience is at present also eliminated by throttling the water with the control valve; however, an air chamber, housed in the tank, ,will better answer the purpose. A pressure reducing valve can also be used, because hammering never occurs at low water pressure; thus it can be seen that the three inconveniences described in paragraphs 1), c, and d, can all be prevented by the same medium, namely by a pressure reducing valve.

This tank or container differsfrom the ordinary flushing tanks at present in use, as it is operated from the side instead of from the front,

and it does not contain the flushing water, but collects all leakage and the exhaust from the auxiliary valve, and conveys them into the bowl, and in combination with the other members housed therein, prevents back-siphoning, noisy flushing, hammering, and failure to flush, in the manner above described.

The foregoing objects and advantages with my subsequent features that may be developed in the description, may be best appreciated from. a

Fig. 8 represents a plan view of Fig. '7.

Fig. 9 represents another form of the invention when the flush valve is not housed in the tank.

The construction of my invention shown in Figs. 1, 2, 3, 4, 5, 6, '7, 8, and 9, inclusive, is as follows:

i, in Fig. 1 represents a tank or container in combination with a closet bowl, housing a flushing apparatus; this form eliminates back-siphoning, allows the air constantly under the undersurface of auxiliary valve 29 and the water discharging therefrom and any leakage from the flushing mechanism is collected in the tank and conveyed into the bowl. Orifice A is to allow the water from the flush valve to enter the rim through passage C and into the bowl, through perforations under said rim, and with orifice B to allow the leakage collected by the tank to drop into the bowl through passage B and perforations under the rim. Said tank is also provided with port E to connect flush valve 9 with operating handle 8, which protrudes outside the tank to operate said flush valve, and to allow the air to enter the tank; port F to allow supply pipe 8-2 to be connected to flush valve 9, and to also allow the air to enter said container, jet supply conduit I0 carries at the top end, extension i, which in combination therewith forms a bolt-like member to fasten tank 1 to bowl [2 by tightening nut l3, the other end of extension H carries fiush valve 9 protruding at one side; this arrangement eliminates the'spud and tail piece which usually connect the flush valve to the bowl, thus leaving a space between the outlet of the valve and the top of the bowl. It is obvious that this non-continuity of conduit from the valve to the bowl positively eliminates backsiphoning under the action of vacuum of any intensity or duration. Funne1 l4, inserted into orifice A is for the purpose of preventing the water from overflowing, and to convey the same into the bowl; this is obtained in combination with the bowl, provided with suitably sized passage therein and proportionally sized perforations under the rim to prevent back-building of the water, and in combination with member I5 extending downwardly to a suitable depth, obtains the inrush of air, thus acting as an injector.

This mechanism practically substitutes the usual tail piece which conveys the water into the bowl. Said member i5 is provided at the upper end with ports I6 for the air supply for the free flowing of water from the outlet of flush valve 9, and at the lower end is provided with screen l8 to reduce the noise of the flowing water; also to keep ring [9 in position and to facilitate the removal thereof. Cover 20 of tank or container,

.when removed, allows free access to the apparavent leakage and to give flexibility, thus preventing possible breaking of the parts when they are assembled, in case of imperfections. All the foregoing described characteristics of members I0, H, M, [5, l8, and I!) are a part of this invention, as they all cooperate with the tank to obtain the wanted result, namely; elimination of back-siphoning, to obtain air constantly under the undersurface of auxiliary valve 29, and to prevent spilling of water from the container to the floor.

The major characteristics of flush valve 9 are not here described, as they form the subject of patent pending application Ser. No. 725,438, filed May 14, 1934.

Fig. 2 represents another form of a tank or container, housing a flushing apparatus. This form has the same prerogatives as the forms illustrated in Fig. l and described above, but differs inasmuch as it has an air chamber 21 to prevent knocking, and tank 1 is lower and extension 32 is higher, thus creating two containers R and S. Container R substituting funnel I4, shown in Fig. l and container S housing air chamber 21, provided with conduit 28, protruding downwardly to prevent the air therein from escaping, thus preventing hammering; one end connected to supply pipeline 82, the other end to flush valve 9 by nipple 31; this valve does not differ practically from the flush valve 9 shown in patent pending application Ser. No. 725,438, filed May 14, 1934. Operating handle 8, extension ll, conduit ID are for the same purpose, and practically the same as shown in Fig. 1 and described above. Passages C, D and ports E and F are of the same character and for the same purpose as those shown in Fig. 1, but orifice B shown in Fig. 1 is substituted by annular space T formed by the inside wall of container S and the outside diameter of air chamber 27. Ring i9 is kept in position by member 15 provided at the upper end with air inlet I6 to ease the flow of water from the flush valve, and at the lower end is provided with screen 18 to minimize the noise of the flowing water, practically the same device as shown in Fig. 1. Cone I l-2 forms an annular space in combination with member i5 which prevents overflow from container B owing to the onrush of the air therein, and also allows the water collected in the tank, to be conveyed through said annular space into the bowl practically in the same way as the annular space T formed by air chamber 21 in combination with container S.

Fig. 3 is a fragment of an elevation side-view, sectioned on line A-F of Fig. 2, showing the side structure of bowl l2, tank '1 and cover 20 thereof, and only the mechanism Structure of the complete jet supply conduit,'-consisting of extension l! which in combination with conduit it? forms a bolt-'likeme mber which connects tank lfirmly to bowl [2, by means of nut l3, and

.jet supply conduit 23 connected to member Ill with nut 26, and the lower end which carries nozzle Fig. 4 represents another'form of the invention,

showing the tank or container housing a pressure reducingvalve and a strainer, besides a flush valve.

This form, in addition to being 100% siphonproof, as the other forms in Figs. '1 and 2, also eliminates the necessityof throttling the control valve, which is customary in the preventionof knocking, or of noisy flushing, and from which method derives the failure of flushing, more specifically described in paragraphs 22,0, and d, also the pressure reducing valve eliminates the knocking of the water without the use of an air chamber, as shown in Fig. 2.

This form shows tank I in one piece with bowl it, a pressure reducing valve 36 of an ordinary type, connected to flush valve 9 by nipple 3'! and to strainer 38 by nipple 39; this strainer isprovided at the lower end with water supply 8--2 entering tank I through opening G, provided with leakproof slip-joint 4U; outlet 64 is connected by nipple 39 to pressure reducing valve 3%, as more clearly shown in Fig. 6. Flush valveQ is of an ordinary piston type, and of course is not the same as the three-cycle type that carries a separate jet contrivance, as shown in Figs. 1, 2, and 3, and above described; nevertheless it has some characteristics of its own, namely:

(a) Auxiliary valve mechanism 4'! is separate from the body of flush valve 9, and is carried by strainer 38 and. connected to valve 9 by slip-joint tube 52 and nuts 63, and is operated by ordinary handle mechanism 8 connected thereto, through perforation E on the tank 1.

(11) Seat M; of piston valve 45 is elongated downwardly, thus forming a sleeve, which in cooperation With the lower end' of valve shell 9, provided with air ports 46 will act as an air injector, either when the flushing water rushes through thus. preventing spilling, or under the action of the vacuum, in case it occurs in the supply pipeline, thus preventing back-siphoning.

(.0). Outlet M for the flushing water is located atone side of the flush-valve shell, carrying member 46 to convey the water into bowl i2 through spud 69. and opening 5! carried by bowl l2.

-Said member 48 is provided with flange 5!, which is connected to flange 52 carried by spud member 69, held firmly together by bolts 53, thus forming the conduit which substitutes the usual tail piece that conveys the flushing water into the bowl. Boltsfiii are suitably disposed to fasten or unfasten them. I

(d) The water from dash-pot M discharges into the tank when auxiliary valve 29 is operated by handleil; this disposition of auxiliary valve mechanism allows the air to enter the valve when under the action of vacuum directly from the atmosphere, instead of as inordinary flush'valves the same purpose as'the other forms.

topassthroughthe rim ports of the bowl, from which the-motive power of the vacuum can draw pollution back into the watersupply.

Fig. 5 is a plan view of Fig. 4, showing a fragmentof bowl l2 and tank '5,- more clearly showing the disposition of the various mechanism housedtherein, namely: flush valve 9 carrying offset 5 l,*au-xilia-ry valve mechanism 45 attached thereto byslip-joint conduit tube 42 and nuts 43 and strainer 38' attached to pressure reducing valve 38 connected to flush valve by nipple 3i. Perforations 58 on bowl 12 are the usual means to attach the toilet seat to the bowl. Opening 59 and ribs 6b are to convey any water that has been collected in the tank, into the bowl. This type prevents any water from the bowl, if it overflowa'to enter the tank.

Fig. 6 is an elevation view on lines A--B--CD of Fig. 5, whichshowsa fragment of bowl H in one piece with tank 1, which, instead of con-- veying the exhaust or leakage from the housed mechanism into, the bowl from the inside of the tankyconveys saidleakage from the outside of the .tank,fthrough port 59 and guided by ribs 60, and being located above the level of the upper end of the bowl, in case this overflows, the Water from the bowl will be prevented from entering the tank or container. This view shows clearly the construction of strainerapparatus 38, showing clearly the. water supply conduit 8---2 discharging into conduit 6| travelling upwardly and entering strainer, 62, from which the water, free of any matter, enters chamber 63, which is pro-- vided with outlet 64 (shown in dotted line to facilitate the reading of this drawing, but the real position is shown in Figs. 4 and 5), connected to pressure reducing valve lit by means of nipple 39 Cap 65, when removed allows strainer 62 to be taken out by handle 66, to clean it from any matter caught therein. Annular offset 51 from the shell of the strainer isto hold aut-1- ilia'ry valve 41', provided with conduit 42 and nuts 43,to be connectedto flush valve 9, as more clearly shown ,inFig. 4;

Fig. 7 is another form of the invention, showing a small fragment of bowl l2 in one piece with tank 1: Thislform has the characteristic of two separate air inlet contrivances to prevent backsiphoning; one is formed'by tail piece 10, provided with air ports 46, carrying at the. top extension 1l,-the top end of which is connected to flush valve 9 and the other is formed by air inlet '68, located above the former one, and on the shellof valve 9, provided with conduit 69, discharging-the air under the undersurface of piston valve 45, and the undersurface of auxiliary valve 29 is also exposed and for the same purpose as shown in Figs. 1, 2, and 4, andabove described. This will allow the air to enter freely into dashpot chamber M, thus preventing piston valve from opening under the action of the vacuum, as specifically describedin Fig. 4, paragraph d. The exhaust from valve 29 through the open bottom '51 of auxiliary valve mechanism 4| drops into tank 1 and passing through opening 59 located above upper end of bowl and guided by ribs 68 is conveyed into the bowl.

In substance, this form shown in Fig. 7 is for In fact, the container housing 'a flush valve, provided with contrivances to prevent back-siphoning, and the aininlet thereof is also supplied from the inside of the tank, by means of ports or perforations thereon; it also housesan auxiliary valve mechanism;- the discha-rge of leakage therefrom is also collected by the tank, and conveyed therefrom into the bowl, and finally the flush valve is operated by handle mechanism protruding outside the tank.

Fig. 8 is a plan view of Fig. '7 showing tank 1, a small fragment of bowl I2 formed in one piece with tank or container 1. It clearly shows the disposition of the flushing apparatus, water supply conduit 82 entering from one side of the tank, and connected to flush valve 9, which carries the auxiliary valve mechanism 4| operated by handle 8, protruding from the tank, and port 59 to allow any water dropping into the tank, to be conveyed by means of ribs 60 into the bowl.

Fig. 9 shows container 1 housing a contrivance to prevent back-siphoning, almost similar to the one shown in Fig. 1, formed by funnel I4, inserted and fitting tightly into member 13; the top end of funnel I4 carries member 14, provided with air inlet 15, and conically shaped extension 16 receiving tail-piece member I1, extending downwardly at a suitable depth into extension 16, thus forming annular space 18, and injector like contrivance to allow the air to rush in under the action of the onrush of the water from flush valve 9, thus preventing the water from overflowing from the funnel. Tail piece 11 is provided with flange I8 and ports l6, and is threaded to receive flanged nut 19 to tighten tail-piece 11 in position, which at the upper end carries flush valve 9, and is provided with air inlets 8|], to supply air to the inside top of tail piece 11, to allow the water to flow freely from outlet 8| of flush valve 9. Control valve 82 is connected to the water supply, the other end is connected to flush valve 9 by nipple 83; handle 8 is to operate the flush valve; 20 is the cover of the tank, to which is fastened the flush valve by flange 18 and nut 19, provided with packing 81; nut 85 is provided under the undersurface with three ribs 88, thus forming three spaces large enough to convey all the water collected from any source by the tank, into the bowl, through annular space 89 and port holes 90, by tail-piece 9|, the lower end of which is connected to the bowl; the air supplied into the tank, enters from ports 92 located in any suitable place'on the tank. This form of the invention does not differ from the others, except that the flush valve is not housed in the tank, but it houses the mechanismpreventing back-siphoning, which receives the air supply from the inside of the tank, entering through openings suitably located on the walls of said tank. To allow the water to flow freely from the outlet of the flush valve into the bowl, the air also is provided from the inside of the tank, same as in the other types above described, and finally, any leakage dropping into the tank is collected by the same, and conveyed into the bowl, the same as in the other forms of the invention. This tank can be of the ordinary type at present in use, and therefore, can be fastened to the wall; old tanks can also be used by making on them the required perforations for the parts that have to be attached thereto, or housed therein. The flush valves at present in use, none of which are siphon-proof are made relatively safe by means of vacuum breakers and check valves, but when used in combination with this apparatus, as shown in Fig. 9, all types of flushing valves are made 100% siphon-proof without the aid of any of the above mentioned, unreliable contrivances.

From the foregoing description, it will be seen that the purpose of my invention has been accomplished by the device as shown, economically and without complications, and by having reduced to practice said invention, the advantages described herein have proven to be real facts.

Obviously, other forms will readily suggest themselves, it is therefore my intention to include all such forms and modifications of my invention that come within the range and scope'of the invention, as expressed in the appended claims.
